Abstract

Relatively few studies have examined fine-scale habitat use of crayfish in headwater streams, despite increasing awareness of the importance of such habitats. Orconectes meeki meeki, Meek’s crayfish, is endemic to the upper White River drainage of Missouri and Arkansas, and Orconectes williamsi, Williams’ crayfish, occurs only there and in the Arkansas River drainage. Our objective was to describe speciesspecific habitat use of these crayfishes at two spatial scales (pool-riffle and microhabitat) within a seasonally intermittent stream. From May through August 2008, we sampled ten riffles and five pools in Rock Creek, Missouri, to quantify surface and hyporheic environmental variables. Density of O. m. meeki was similar between riffles and pools; O. williamsi density was greater in riffles. At the riffle scale, O. m. meeki was positively associated with wetted channel width and upwelling hyporheic zones; O. williamsi was negatively associated with surface and hyporheic water temperatures. At the microhabitat scale within riffles, O. m. meeki was positively associated with wetted depth and pebble-cobble substrates; O. williamsi was positively associated with surface velocity and pebble-cobble substrates. Habitat use was relatively static for both species as surface flows waned from May through August. Our research provides detailed, fine-scale habitat associations of the crayfish to complement existing knowledge of these species at coarser spatial scales.
